Be it known that 1, CHARLES GIIEsEBRoUen \Vooos, a citizen of the United States, residing at Easton, Pennsylvania, have invented certain new and useful Improvements in Can- Tops. of which the following is a Specification.

My invention relates to packing vessels,par ticularly to those designed for containing powders---such, for instance, as talcum powder, which is liable to sift through any loosejoints between the closing-plate and the cap.

My invention relates more particularly to the finger-piece for operating the closingplate, whereby a piece of considerable depth or one presenting a considerable depth of side is presented, against which the pressure of the finger is brought, so that in the operation of the closing-plate the finger will not beinjurcd, as is often the case in ordinarydevices of this character wherein the finger-piece is simply a flat extension of the closing-plate and presents a raw thin edge for contact with the fingers. In devising my improvement I have also had in mind the necessity of providing a linger piece which will act as a rigid or unyielding stop to arrest the turning movement of the closing-plate in contradistinction to the finger-piece, which, as before stated, is simply a flat extension of the closing-plate and is liable to spring up over the stops on the cap, and thus pry up the closingplate from the surface of the cap, thus providing an opening or a looseness between the parts allowing the sifting of the powder out from the receptacle.

In the accompanying drawings, Figure 1 is a plan view of one form of my invention. Fig. .2 is a sectional view through the same. .Fig. 3 is a detailed edge view of the closingplate with its lug. Fig. 4: is a plan view of another form of the invention. Fig. 5 is a bottom plan view of the closing-plate of Fig. at, and Fig. 6 is an edge view of the closingplate of Fig. i.

In the drawings, 1 indicates the can-cap, having an opening, as at 2, through which the powder or other material is to be discharged. The can-cap has a raised central portion 3, in which the said opening is formed, and resting and turning upon this raised central portion is a closing-plate 1, which is provided with openings 5 6, adapted to be brought into register with the opening through the capplate for the discharge of the contents. This closing-plate has a depending flange 7 around its edge fitting against the shoulder 8, provided by the raised central portion of the cap, which flange serves for stiffening the closingplate and preventing it from being pried up under ordinary usage.

The finger-piece consists in Fig. 1 of an integral extension 9 of the metal of the closing-plate, said extension being in the plane of the lower edge of the flange of the closingplate, the said extension having a portion 10 connected therewith at one side integrally, which portion is of curved or arched form, extending from side to side of the extension 9 and resting with its free edge, as shown in Fig. 3, at 11 upon the upper side of' the said extension. This arch or curved form of finger-piece, it will be noticed, presents rounded side edges along its sides for contact with the fingers, the curve or convexity of the fingerpiece being in a direction transverse to the radius of the closing-plate. The construction presents a finger-piece of considerable height and having a rounded surface. It may be forced in either direction by the finger without causing damage to the finger or linger-nail. The arch, as shown in Fig. 3, may extend above the plane of the upper surface of the closingplate, or it may be of less height, if desired.

In Figs. 1, 5, and 6 the closing-plates are shown of substantially the same form as that above described, and the linger-piece in this instance has the same general characteristics as that mentioned above in that it is curved in a direction transverse to the radius of the closing-plate, presenting a piece of considerable height for contact with the fingers and a convex or substantially convex upper surface. In forming this finger-piece an extension of the metal closing-plate is provided, and this extension is curved or arched transversely, as shown.

Not only does the linger-piece, when constructed as above described insure easy and safe operation of the closing-plate, but a rigidity of constructionis aiforded by such a finger-piece which will resist all tendency of the fingerpiece to ride up onto the stops 12 formed on the can-cap, against which the side of the finger-piece is adapted to strike and act as a limiting means.

I claim as my invention 1. A closing-plate for cans or like receptacles having a finger-piece of substantially arched form, the curve of the arch being in a direction transversely of the radius of the closing-plate,and extending from edge to edge 7 adapted to strike the said stops, substantially as described.

3. A closing-plate for cans or like receptacles having a linger-piece formed of an integral extension with its sides turned down- Wardly, substantially as described.

4. A closing-plate for receptacles havinga finger-piece formed of an integral extension, the said extension being provided With an arched portion extending over the same, the said extension projecting radially of the plate and the arch being transverse to the radius of said plate, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.

CHARLES CHESEBROUGH WOODS.
